When i test the application using mvn gwt:run it throws an error Caused by: com.google.gwt.dev.shell.HostedModeException: Something other than an int was returned from JSNI method '@com.google.gwt.valuestore.shared.impl.RecordJsoI mpl::getInt(Ljava/lang/String; )': JS value of type undefined, expected int at com.google.gwt.dev.shell.JsValueGlue.getIntRange(J sValueGlue.java:266)

If i remove the studentAge field from the script and create the project, it runs just fine. Could there be an issue with integer datatypes in entities and GWT?
